Reprocess of my Leo Triplet data

[michael.h.f.wilkinson]

Had a bash at reducing the colour noise in the background, and fiddled with curves on my 5 hours of integration time. I basically reduce saturation in the areas of low luminance. I really want to do this more selectively, and write  method to enhance saturation only in significant objects, and not in noisy areas. Might set up a student project for that. All data acquired with my Meade SN6 6" F/5 Schmidt-Newtonian and ASI183MC (not cooled) camera on Vixen GP-DX mount.

Version one

 

Version two, a bit lighter in the background:

It seems to depend on the monitor which I like best.

Next year, I plan to get a load more data to combine with this set.

Number two floats my boat, lovely images.

THAT is a spectacular image. I like both versions. The lighter version seems to show a bit of gradient or amp glow around the edges so I prefer the darker one.

FYI, I'm not even sure if it's possible to image this, but on 16 May comet Shoemaker 155P will transit across M65. It will only be approx. mag. 16.7 so I do not know if it will show up in images or not.
